The Case Of The Flat Tires
Did some detective work to figure out why I had a flat issues at my last race. I checked the two tubes that went flat and discovered that one of them was from a puncture on the outside (thorn glass or sharp rock) and the other from the inside (a problem with my rim or rim strip). I thought I was dealing with one serial puncturer but I was wrong two puncturers had been responsible for foiling my race.
I did some more sleuthing to find a sharp area where the loop of the wheel came together. I sanded down the sharp spot. put a new rim strip on and checked for sharp objects in my tire
Hopefully this mystery is solved. If I get another flat at the Norcross Scurry race this weekend I will reopen the case.
